Garlic oil is vulnerable to economically motivated adulteration and misleading or false labeling. ISO 17025-accredited natural products testing lab Beta Analytic selected garlic oil as subject of a case study precisely because of these reasons and to highlight the need for strict quality control measures for essential oils.
Beta Analytic tested five garlic oil samples available in the market – four products marketed as natural and one labeled clearly as artificial garlic oil. Gas chromatography-mass spectrometry (GC-MS) results showed that all five samples have the chemical composition of garlic oil. Only carbon-14 analysis was able to identify the presence of petrochemical-derived adulterants and verify the natural source of the samples.
Carbon-14 testing will enhance a manufacturer’s quality control measures by providing data that cannot be supplied by other tests often used in the industry to detect adulteration.
For more information, please read Beta Analytic’s article “Quality Assurance Testing: Is your Garlic Oil Natural?” published in Nutraceuticals World. The lab provided details on the GC-MS and Carbon-14 test results as well as a backdrop of garlic oil adulteration.
Based in Miami, Florida, Beta Analytic provides fast, high-quality natural vs synthetic essential oil testing by carbon-14 analysis.
